Scott and Rep. John Lewis (D-GA) are two prime examples of black political leaders who signed on early with the Clinton camp, but who are now feeling the heat from their community after the Obama Rush of recent weeks.

There is no group of superdelegates more under the gun than black lawmakers in the Congress, or black elected officials at any level.

At this point, if you aren't on the Obama Bandwagon, there are going to be a lot of people asking why.

I thought a lot about this while I was on the road in South Carolina, where a number of veteran black state lawmakers very publicly supported Hillary Clinton at her campaign events, and then watched as she went down in flames in the Palmetto State.

All I could think was how vulnerable those same elected officials now must look to younger blacks who were thinking about running for office.

The switch is also a microcosm of one of the problems faced by the Clinton campaign right now - the switch of just one delegate every day makes news and reinforces the notion of Obama Momentum.

It won't surprise me to see more black lawmakers in Congress switch as well, especially if their districts went by huge majorities for Obama.
